Hypertensive Urgency Management

Definition and Diagnosis

Hypertensive urgency is defined as severely elevated blood pressure (>180/120 mmHg) without acute target organ damage and should be managed with oral antihypertensive medications and outpatient follow-up, according to the American College of Emergency Physicians 1, 2, 3
The presence or absence of acute target organ damage is the sole determining factor that differentiates hypertensive urgency from hypertensive emergency, not the absolute blood pressure number itself 1, 3
Verify blood pressure >180/120 mmHg with repeat measurement using proper technique to exclude white coat effect or measurement error 1, 3

Neurologic assessment should look for altered mental status, somnolence, lethargy, headache with vomiting, visual disturbances, seizures, or focal neurologic deficits, which indicate hypertensive emergency 1, 3
Cardiac assessment should evaluate for chest pain suggesting acute myocardial ischemia/infarction, dyspnea suggesting acute heart failure or pulmonary edema, which indicate emergency 1, 3
Vascular assessment should assess for symptoms of aortic dissection, such as tearing chest/back pain, pulse differentials, which indicate emergency 1, 3
Renal assessment should check for acute deterioration in renal function or oliguria, which indicate emergency 1, 3
Ophthalmologic assessment should perform fundoscopy for blood pressure ≥180/110 mmHg to look for bilateral retinal hemorrhages, cotton wool spots, or papilledema, which indicate malignant hypertension 4, 1, 2

The American College of Emergency Physicians recommends managing severely elevated blood pressure without acute organ damage with oral medications and outpatient follow-up, and that hospital admission and IV medications are NOT necessary 1, 2, 3
Target gradual blood pressure reduction over 24-48 hours, with a goal of reaching target blood pressure of <130/80 mmHg (or <140/90 mmHg in elderly/frail patients) within 3 months 1, 2, 4
Avoid rapid blood pressure reduction, as this may cause cerebral, renal, or coronary ischemia in patients with chronic hypertension who have altered autoregulation 1, 2, 4
For Non-Black Patients, start low-dose ACE inhibitor or ARB as first-line therapy, and add dihydropyridine calcium channel blocker if needed as second-line 1
For Black Patients, start low-dose ARB plus dihydropyridine calcium channel blocker OR calcium channel blocker plus thiazide/thiazide-like diuretic as first-line combination 1
For Patients with Heart Failure, prioritize ACE inhibitor or ARB as first-line, and add beta-blocker as second-line 2
For Patients with Cardiovascular Disease, target systolic blood pressure of 120-129 mmHg to reduce cardiovascular risk, and consider fixed-dose single-pill combination treatment to improve adherence 1, 2

Schedule outpatient follow-up within 2-4 weeks to assess response to therapy, and ensure continuing outpatient care is arranged before discharge from the emergency department 1, 2, 3
Patients should be monitored at least monthly until target blood pressure is reached 1

Do NOT admit patients with asymptomatic hypertension without evidence of acute target organ damage, as this represents overtreatment and inappropriate resource utilization 1, 2
Do NOT use IV medications for hypertensive urgency, as oral therapy is appropriate and IV therapy may cause harm through excessive blood pressure drops 1, 2, 3
Do NOT rapidly lower blood pressure in hypertensive urgency, as rapid reduction may precipitate cerebral, renal, or coronary ischemia, particularly in patients with chronic hypertension who have altered autoregulation 1, 2, 4
Do NOT use short-acting nifedipine in the initial treatment of hypertensive urgency, as this agent causes unpredictable precipitous blood pressure drops and reflex tachycardia 1, 2
Do NOT confuse subconjunctival hemorrhage or isolated epistaxis with malignant hypertensive retinopathy, as these are NOT acute target organ damage and do not require emergency management 1
Do NOT initiate treatment for asymptomatic hypertension in the emergency department when patients have follow-up arranged, as this is not necessary and may be harmful 1, 2
